7 Claims. 1

This invention relates to improvements in drawer slide actuatingmechanism for cabinets and the like.

The main objects of this invention are:

First, to provide a drawer slide actuating mechanism for phonographcabinets and the like in which the drawer slide is automaticallywithdrawn and returned or moved into the compartment with the openingand closing of the door.

Second, to provide a drawer slide mechanism which may be readily appliedto numerous conventional types of cabinets or compartments equipped withdrawer slides or slidable supports.

Third, to provide a mechanism of this character which is easy ofoperation and one which does not subject the cooperating parts to unduestrain.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

Fig. 17 is a fragmentary View in section on line lI-l1 of Fig. 16.

In the embodiment of my invention illustrated in Figs. 1 to 6 inclusiveI illustrate my invention in a phonograph cabinet in which i illustratesthe cabinet generally, 2 the playing compartment which is provided witha drawer slide 3, the compartment door 5 being hinged at 5. The drawerslide 3 is mounted on the slide rails 6 and provided with a carriage ltraveling thereon, this drawer mounting feature being that shown in myPatent 2,370,861 issued March 6, 1945. This mounting is advantageous inthis connection as it provides a freely slidable drawer slide or recordsupport and one which does not bind as it is moved back and forth intothe cabinet. The main purpose of withdrawal of the slide is tofacilitate changing of the records conventionally shown at 8.

My mechanism is designed to provide means whereby the drawer slide isautomatically withdrawn from and retracted or moved into the compartmentwith the opening and closing of the door. In the embodiment shown inFigs. 1 to 6, this mechanism comprises a forwardly curved rod-like cammember 9 terminating in a gooseneck bend at It and flattened to providean attaching plate or bracket II. The cam member is attached adjacentthe hinged edge of the door and on the inner side thereof to projectrearwardly under the drawer slide. In this embodiment, I provide acoacting pair of grooved cam follower rollers l2 having journals I3carried by the support M which is pivotally mounted at IS on theattaching bracket Hi. This permits the rollers to freely travel alongthe opposed sides of the cam member and to swing to prevent binding. Theportion [7 of the cam member between the goose-neck bend It and the freeend of the cam member is curved longitudinally away from the door toretard the movement of the slide as the door approaches the outer limitof its opening movement. To prevent the slide contacting the door as thesame is opened the slide has a bevel 58 at its front corner adjacent thedoor hinge. The cam member 9 is preferably formed of a section of rod.While it appears to be of substantially uniform curvature, the dwellportion results from the relationship of the cam member to the hinge ofthe door. With this arrangement, the door may be easily opened and, asstated, the drawer slide is withdrawn from and moved into thecompartment by the opening and closing of the door.

In Figs. 7 to 9 inclusive I show an embodiment of my invention adaptedto a door 23 hinged at El, the hinges being disposed horizontally. Inthis case, the cam member 22 is substantially the same as thatdescribed, its attaching plate 23 bein an extension of the cam member tofacilitate mounting on the door, with the cam member projecting upwardlyat one edge of the drawer slide 3. The mounting bracket 2A for thesupport pivoted thereto for the cam follower rollers 25 is in the formof an angled plate, the angle embracing the edge of the drawer slide 3.The operation is the same as described.

In the embodiment of my invention shown in Figs. to inclusive, the cammember 26 is in the form of a sheet metal stamping, terminating at itsinner end in an attaching plate 21 secured to the inner side of the doorl which in this embodiment is provided with vertical hinges. The drawerslide has the same mounting. This cam member 26 is provided with anangular cam slot 28 while the drawer slide is provided with a camfollower roller 29- engaging the slot. The inner portion 3 3 of the camslot is conformed substantially in the arc of a circle, the center ofwhich is substantially in alinement with the axis of the hinge 5 so asto permit a substantial opening of the door before imparting movement tothe drawer slide.

In Figs. 16 and 1'7 I illustrate an embodiment in which the cam member28 is applied to a door hinged at its lower edge. In this case, the cammember 26 is disposed at the side of the drawer slide 3, the bracket 31for the cam follower 29 projecting upwardly from the edge of the drawerslide as clearly illustrated.

In both cases, the cam slot is formed so that its inner portionconstitutes a dwell-producing portion with which the follower coactsduring the initial opening movement of the door thereby providingclearance for the drawer slide.

I have illustrated and described commercial embodiments of my inventionwhich are highly practical. I have not attempted to illustrate ordescribe other embodiments or adaptations which might be desired forparticular cabinet structures or compartment structures and/or slides asit is believed that this disclosure will enable those skilled in the artto embody or adapt my invention as may be desired.
